If Bloomingdale is the same Bloomingdale Google Maps tells me is in the middle of Manhattan and 2 blocks from Central Park NYC, yes, it is an enclave of wealth and privilege. Try riding your bike around the Bronx some time, it'll broaden your world view.

There's a world of difference between a public school in a wealthy area and one in a shitty one. The former might as well be a private school in terms of the quality of instruction and available funding from PTA donations.
